# Symbol
Symbols are a unique and immutable primitive data type in JavaScript, introduced in ECMAScript 6 (ES6). They are often used to create unique property keys for objects, ensuring that no property key collisions occur. Each Symbol value is unique, even if created with the same description. Symbols can be created using the Symbol() function, and their primary use case is to add hidden or special properties to objects that won’t interfere with other properties or methods.
